Clarksville Fire Rescue’s Operations division is made up of 3 shifts of 61 personnel per shift. Each shift has 1 Assistant Chief, 1 District Chief, 1 Captain, and 10 Lieutenants. The operations division works a 24 hours on and 48 hours off schedule. When the persons of each shift are not fighting fires, responding to motor vehicle accidents, or medical calls they perform other tasks like testing fire hydrants, pre-fire planning, and training. Clarksville Fire Rescue tests over 5000 fire hydrants twice a year color coding them so that the responding unit will know how many gallons per minute the hydrant, that they might need, flows. Pre-fire planning is done to familiarize the crews with commercial buildings in their stations area. Known hazards such as gas and electrical shut offs, are just some of the information gathered. Emergency contact information is also obtained so that if we have an emergency call in the middle of the night or on a weekend we know who to contact to gain access. The training is described under the training section.
